The package is intended for scientists and engineers who need to manipulate a variety of types of matrices using standard matrix operations. Emphasis is on the kind of operations needed in statistical calculations such as least squares, linear equation solve and eigenvalues.

Ngraph is prepared to plot 2-dimensional graph for students, scientists and engineers. The program reads numerical data from general ASCII text files, and plot to graph. ** Tips ** - This program support Kanji font. If you want to use it, please set environment variable LANG to ja_JP.EUC. (cf, under csh/tcsh) % setenv LANG ja_JP.EUC and you need.... - kinput2 - X True Type or X True Type Font server[best], or kanji18 and kanji26 fonts, these fonts are in below ports[better], - ja-ngraph-fonts (japanese/ngraph-fonts) - ja-kanji18 (japanese/kanji18) - ja-kanji26 (japanese/kanji26) or to change font name in Ngraph.ini as below[poor]. font_map=Mincho,1,-*-fixed-medium-r-normal--*-*-75-75-c-*-jisx0208.1983-0 font_map=Gothic,1,-*-fixed-medium-r-normal--*-*-75-75-c-*-jisx0208.1983-0 - You can get documentation in Japanese from below URL. ** Acknowledgements to this ports file ** Special thanks to: Satoshi Ishizaka <isizaka@msa.biglobe.ne.jp> Nobuhiro Yasutomi <nobu@rd.isac.co.jp>

libocas implements an Optimized Cutting Plane Algorithm (OCAS) for training linear SVM classifiers from large-scale data. The computational effort of OCAS scales with O(m log m) where m is the sample size. In an extensive empirical evaluation, OCAS significantly outperforms current state-of-the-art SVM solvers. libocas also implements the COFFIN framework for efficient training of translation invariant image classifiers from virtual examples.

Library and cli utility for reading data from OriginLab OPJ project files. Supported OPJ versions: 6.0 - 8.1 Usage: opj2dat <project.opj>

A Double-Double and Quad-Double Arithmetic library. Double-double and quad-double numbers are unevaluated sum of two and four IEEE doubles capable of representing 106 and 212 bits of significand, respectively. The library is written in C++, taking full advantage of operator overloading. C, Fortran 77, and Fortran 90 interfaces are also provided. This work was done at Lawrence Berkeley National Laboratory, NERSC Division, Yozo Hida with Xiaoye S. Li and David H. Bailey.

Hoc, the High Order Calculator, is an interpreted language for floating-point calculations. Its most basic use is as a powerful and convenient calculator, interactively evaluating expressions such as 1+2*sin(0.7). But hoc is no ordinary calculator: It also lets you assign values to variables, define your own functions, and use loops, conditionals, and everything else you'd expect in a programming language. Hoc was developed by Brian Kernighan and Rob Pike, and introduced in their 1984 book The Unix Programming Environment. This version has been extended and improved by Nadav Y. Har'El.

The general purpose of this library is to provide C language procedures related to cartographic processes. Procedures for each of the processes will be strictly categorized and although they may share common subfunctions they will not intersect in scope.

Qalculate! is a multi-purpose desktop calculator. It is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface.

libranlip is a C++ library created by G. Beliakov, which generates random variates with arbitrary Lipschitz-continuous densities via the acceptance / rejection method. The density should have a dimension of no more than about five. The user needs to supply the density function using a simple syntax, and then call the methods of construction and generation provided in libranlip.

LibTomMath provides highly optimized and portable routines for a vast majority of integer based number theoretic applications (including public key cryptography).
